In-Plane Analysis of Masonry Infill Materials

Abstract

Simple methods for determining the corner crushing strength and the in-plane stiffness of masonry infills are developed. The methods are applicable to structural clay tile, clay brick, and concrete masonry infills and to both steel and concrete bounding frames. The corner crushing strength is determined as a function of the infill thickness and the infill prism compressive strength. The stiffness is determined using a stepwise function of the displacement and is a function of the relative stiffness of the infill to the frame. The only infill material property required for the stiffness is the modulus of elasticity. The methods were developed by looking at a wide variety of tests as reported in the literature.
